In the context of the new era, the public security situation has undergone tremendous changes, which is a challenge to the public security organs, especially the criminal investigation departments.

However, the development of science and technology is also changing with each passing day, and high technology has given the public security organs many new investigative methods, and many things that were unimaginable before are now not so science fiction, but have even been applied to actual combat.

The GPS positioning system installed on the second luxury business car rented by Yang Jiandong's gang is very advanced, and the recorded and preserved vehicle trajectory is both clear and accurate.

What's even more exciting is that the places where luxury business vehicles have stayed are either high-end residential areas or bustling commercial districts, or development zones and industrial parks. It is impossible for these places to be without surveillance, as long as the surveillance video is called out, you can find out what they are doing, and you can find out who has been in contact with them.

Teng Jiming believed that he was infinitely close to the truth, and as long as he persevered, he could catch the murderer, although he was very sleepy and tired, he still insisted on fighting at night in the special case command to study the next stage of deployment.

"Lao Ji, the Kaijing County Public Security Bureau has assisted us in investigating for so many days, and the police have been arranged in the place where the squatting should be controlled, if Yang Jiandong really absconds back to his hometown, it is impossible not to leave clues, and it is impossible not to have any movement. I analyze that it is unlikely that he will abscond to his hometown, there is no need to squat down anymore, and the manpower here is relatively tight, so you should come back quickly. ”

"It's okay, let's go back first, and then greet the leaders of the Kaijing County Bureau early tomorrow morning. ”

"Well, I want to thank you. ”

On the phone with Lao Ji in Kaijing County, the policeman Xiao Xu pushed the door and rushed into the conference room, ran to the map and pointed to a location marked yesterday evening, and said excitedly: "Report Tengda, the old water conservancy station office building and ancillary facilities were bought by a person named Jiang Hao as early as more than ten years of restructuring, and began to be used as a wharf and freight yard.

Qiuping found Boss Gan and learned that there were only two workers in the paint factory, one surnamed Yu Qinggong and the other surnamed Gan and Gan Xinlan, who were a couple and related to Boss Gan. At this time, they were on their way to Yu Qinggong and his wife's house, and Boss Gan took Qiuping and them there. ”

"Great, call Qiuping and ask them to start the video when they arrive. ”

"Yes!"

There are 21 locations on the map, which means there are 21 places to check.

It's the middle of the night, and I can't even find anyone, how to check, the only thing I can do now is to let the police go over and observe the surrounding environment first, see how many cameras there are near the location where the luxury business vehicle has stayed, and then visit and inquire after dawn, and then find someone to watch the surveillance video.

I thought I would have to wait for at least three or four hours, but I didn't expect Zhang Qiuping's group to be so efficient that they could find someone in the middle of the night.

Teng Jiming lit a cigarette and watched Xiao Xu log in on the laptop> after a while, the WeChat computer prompted someone to send a video call request, Xiao Xu hurriedly clicked the mouse, only to see that the screen was dark, the camera was constantly shaking, and then the screen lit up, and a middle-aged man in his forties appeared in the picture, yawning and asking: "Brother-in-law, what goods are so urgent, even if you are in a hurry, you don't need to run over in the middle of the night, just make a phone call." ”

"Yu Qinggong, we are looking for you!"

Zhang Qiuping and the criminal policeman Xiao Sun squeezed into the living room from Boss Gan's net worth, and showed their documents: "See clearly! We are from the Criminal Police Brigade of the High-tech Zone Bureau, my surname is Zhang, my name is Zhang Qiuping, this is my colleague Sun Renyou, do you know why we are looking for you?"

The Public Security Bureau's is still the criminal police team!

Yu Qinggong was taken aback, and looked stupidly at the two policemen who came to the door in the middle of the night, not knowing what to say or what to do.

"Qinggong, the comrades of the Public Security Bureau will not look for you for no reason, what is going on?" Boss Gan, who was approached by the police in the middle of the night, was also very depressed, and followed up in the living room and glared at his cousin-in-law with hatred.

"Brother-in-law, I'...... I didn't do anything, others don't know you don't know, am I the kind of person who is a traitor?"

Boss Gan knew his cousin-in-law too well, and believed that he would not do anything illegal and criminal, so he turned around and smiled: "Officer Zhang, my brother-in-law is honest, what can he do, you must be mistaken." ”

"Make no mistake," Zhang Qiuping looked back at the bedroom with the door hidden, and his gaze shifted to Yu Qinggong's face: "Let me remind you, where were you on the night of the 27th of last month, who did you see, and what did you do?"

"On the 27th of last month, I, I can't remember. ”

"Think again, think about it. ”

Yu Qinggong really couldn't think of it, and was frowning sadly, his wife Gan Xinlan walked into the bedroom with her clothes on, peeked at Boss Gan, and said nervously: "Comrade Public Security, on the night of the 27th of last month, I, I, I seem to have a little impression. ”

"Say!"

My brother-in-law is right, the police will not come to the door for no reason.

It's really greedy for a small price and a big loss, Gan Xinlan regretted it, and said with a bitter face: "That day, a few bosses borrowed a place to play cards and gave me two hundred yuan, so I opened the door of my brother-in-law's office and let them play inside." ”

What a big deal he thought, Yu Qinggong remembered it, and subconsciously said: "They also gave me two boxes of cigarettes."

"What are the surnames of those bosses and what do they look like?"

……

Zhang Qiuping asked while the iron was hot, the name did not match, but the physical characteristics matched.

Let Yu Qinggong and his wife see the photos of the suspects, and the four suspects, including the victim, are all on the right number!

Yu Qinggong and his wife, who provided the venue, did not know the mobile phone numbers of Yang Jiandong and other suspects, but one thing can be confirmed that Yang Jiandong and others rented a luxury business car to pick up gamblers, and the driving trajectory of the luxury business car was so clear. With the presence of the two witnesses, Yu Qinggong and his wife, it should not be difficult to identify the gambling participants, and it is also not difficult to find out the whereabouts of Yang Jiandong and other suspects through the gambling participants.

Teng Jiming was ecstatic, and was staring at the computer monitor to watch Zhang Qiuping ask, when the police communication suddenly rang, and when he looked at the caller ID, it was actually Deputy Director Feng of the Yandong Branch Bureau.

"Feng Ju, it's so late, you haven't slept either!"

"Lao Teng, don't say polite words, report a situation, our sub-bureau security brigade and Changlin Street Police Station jointly seized a public security case of gambling in the way of 'pulling the rak', and found an important clue in the process of investigation and handling, the person who set up this gambling game is likely to be Yang Jiandong who we want to arrest. ”

Is there any mistake, your sub-bureau found it, and I found it, and I've been checking it all the time!

Teng Jiming was caught off guard, and he didn't know how to pick it up, Feng Ju continued: "It has been confirmed that it is Yang Jiandong who set up the gamble, and his location has been successfully locked, I have rushed to the scene, and the criminal police and special police have all been in place, and they will act on time at 4 o'clock." You may not be able to come over now, but it doesn't matter, he's a murder suspect, and we'll hand him over to the task force as soon as we catch him. ”
